Question details

The user needs to troubleshoot why a looping PowerPoint presentation stops playing unexpectedly after running for an extended period.

How to Fix PowerPoint Slide Show Stopping Randomly During Continuous Playback

Product: Microsoft PowerPoint
Device & OS: not provided
Scenario: Running a continuous, looping presentation on a wireless monitor unattended.
Observed behavior: The 15-slide presentation stops looping randomly after 30 minutes to several hours, despite being configured to repeat continuously.

Before you start

Check your computer's power management settings to ensure the system is configured to never sleep or turn off the display, as power-saving modes will interrupt the presentation.

Solution 1Recommended

Isolate the Wireless Connection and Network Stability

Determine if the issue stems from PowerPoint itself or an unstable wireless monitor connection.

Wireless monitors rely on network protocols like Miracast. If the Wi-Fi drops or the network experiences heavy interference, the display connection will time out, causing the presentation to halt.

Test without the wireless monitor

Disconnect the wireless display and run the presentation directly on the primary computer screen to see if the issue persists.

Check network interruptions

Ensure the Wi-Fi connection is stable. Avoid putting the host device on a congested network where intermittent drops might sever the wireless display link.

Review monitor sleep settings

Access the physical menu or settings app for your wireless monitor/receiver and disable any auto-sleep or inactivity timeout features.

Isolate the Wireless Connection and Network Stability

Testing Tip: If the presentation runs smoothly all day on the local screen but fails when projected wirelessly, the root cause is the wireless connection or monitor settings, not PowerPoint.

Solution 2

Change the Presentation Show Type

Adjusting the show type can prevent background tasks or remote computer access from interrupting the continuous loop.

Frequently Asked Questions

Why does my looping PowerPoint stop when someone else uses the computer?

When a presentation runs in standard full-screen mode, any mouse click or keyboard press outside of the PowerPoint window changes the system focus, which can immediately pause or stop the playback. Changing the show type to 'Browsed by an individual (window)' helps prevent this.

Can a weak Wi-Fi signal stop a wireless presentation?

Yes. Wireless displays typically use protocols that require a continuous, stable Wi-Fi connection. Even a brief network drop can cause the monitor connection to fail, which in turn halts the presentation software.

How do I make sure my computer doesn't go to sleep during a presentation?

Open your computer's Power & Sleep settings. Set both 'Screen' (turn off after) and 'Sleep' (PC goes to sleep after) to 'Never', especially when the device is plugged into a power source.
